FEEDING MECHANISM FOR CARDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 290,758, dated December 25, 1883.

7 Application filed January 2, 1883. (No model) To aZZ whom it may concern:

Be it known that I, SAMUEL DRIVER, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Feeding Mechanism for carding-Machines; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

In a set of woolen-cards the selfacting feeders now used take the sliver from one cardingengine and deliver the same to the next obliquely to the face of the carding-cylinder, so that portions of a number of such slivers are operated upon at the same time. The sliver is delivered by a carrier on an apron or a series of bands, the carrier being reciprocated obliquely by an endless band. At each end of the self-feeding device a knife is hinged, around the edge of which the sliver is carried by the carrier. This knife determines the length of the loop of sliver delivered to the carding-engine. In self-feeders as heretofore constructed the knives were hinged to the end brackets, in which the pulleys carrying the endless belt by which the sliver-carrier is reciprocated are supported. Therefore the knives occupied a fixed position with relation to the carrier at the end of each reciprocation. The sliver, in passing around the knife, was drawn out, so that a much smaller quantity of fiber was delivered to the second and third carding-engine along the edges, and when at the finishing-card the same was delivered to the spindles, the end spindles made a much lighter yarn.

The object of this invention is to obviate this defect and deliver a uniform quantity of sliver to the carding-engine.

The invention consists in so constructing the frame that the carrier and the knife can be adjusted independent of eachv other, and the amount of slack can be regulated, as will be more fully set forth hereinafter.

Figure 1 is a top view of the apron of awoolcarding engine, showing the oblique position of the self-feeding device and other features hereinafter described. Fig. 2 is a view of the self-feeding device, some parts being omitted by reason of the small scale of the drawings.

Fig. 3 is an enlarged view of one end of the self-feeding device, showing the carrier and the knife. This figure shows details of construction, as hereinafter described, some of 5 which are omitted in Fig. 2. Fig. 4 is aview of the pointed angle traversed by the carrier, showing the same in position considerably beyond the knife to lay the sliver. Fig. 5 is a view of the sliver laid by my improved selffeeder. Fig. 6 is aview showing the sliver as laid by the old self-feeder.

In the drawings, a a a are a number of belts, forming an apron, on which the sliver is delivered obliquely to the face of the carding engine.

B is the guide-rod for the self-feeding de vice, extending across the frame, as shown.

C is the carri er, which travels on said rod B.

D D are the knives.

E E are the end pulleys, supported in the adjustable bracket E. The belt 6 passes over the pulleys E E, and is provided with a pin, which enters the slot of the carrier 0, and thereby, in passing around the pulleys E E, traverses the carrier from end to end, and de livers the sliver carried by the same. Motion is imparted to the belt 0 by the beveled gears 1 2. (Shown in Fig. 1.) The bracket E is secured to the frame byabolt, 3, passingthrough the slot 0, and can be readily adjusted to regulate the relation of the knife with the carrier. The knives D D were formerly hinged directly to the bracket E, and could not be adjusted.

d is a slide, provided with a slot, through which a bolt, 4, passes, by which the same is secured to the frame F. A boss on this slide (1 passes through the slot cl in the frame F, and on this boss the knife D is pivotally secured. The slide (1, and with it the knife D, can be adjusted so as to be brought nearer to or farther from the end of the traverse of the carrier, and thereby more or less slack can be secured in laying the sliver around the edge of the knife. By thus adjusting the delivery of the sliver at the ends of the traverse of the carrier all drawing of the sliver in passing around the knife may be avoided, the quantity of sliver delivered to the cards and from the cards to the spindles is uniform throughout, and the resultant yarn may be of uniform weight.

. seams Having thus described my invention, I claim 3. The combination, with the frame F, proas new and desire to secure by Letters Patentvided with the slots 6 and cl, of the adjustable 15 1.
